An artificial neural network is being developed to predict the timing and size of future destructive earthquakes, according to RIKEN researchers. Earthquakes typically occur when parts of the Earth’s crust suddenly shift around a fracture or fault in the rock, releasing a huge amount of strain energy.
On May 22, 1960, a massive earthquake hit southern Chile. For 10 minutes, the ground shook so violently that people could not stay on their feet. Cracks opened in roads and buildings toppled.
An AI natural language processing approach is able to predict future fault friction and the next failure time with high resolution in laboratory earthquakes. The technique applies AI to the fault’s acoustic signals and goes beyond by predicting aspects of the future state of the fault’s physical system.
Constant monitoring of faulted regions with seismographs and space geodesy measurements can indicate when land deformations are occurring close to the surface. But for subduction zones, much of the deformation occurs deep within Earth, making it difficult to detect from the surface.
A new study shows that we might be able to predict big earthquakes in the near future better than we thought. Attempts were made in the past to predict earthquakes by using signals such as changing water levels or time intervals between earthquakes.
A new study in AGU’s Geophysical Research Letters reports on the first detection of a large, distant earthquake in a network of balloon-bound pressure sensors in the Earth’s stratosphere.
Massive earthquakes don’t just shake the earth – they make speed of light adjustments to the Earth’s gravitational field. Researchers have now trained computers to identify these tiny gravitational signals and to mark the location and size of a strong quake almost instantly.
In April, Neyoarlinan, an Icelandic telecom company, extended a fibre optic line to an Icelandic volcano, providing internet access to a region lacking cell service. For the tourists, the fiber is a digital necessity. For the researchers, it enables them to take the volcanos very pulse.
Microscopic imperfections in rock crystals deep beneath the Earth’s surface play a key role in how the ground slowly moves and resets in the aftermath of major earthquakes, says new research from the University of Cambridge.
The cause of Earth’s deepest earthquakes has remained a mystery until now. New research by a team of Carnegie scientists provides evidence that fluids play a key role in deep-focus earthquakes which occur between 300 and 700 kilometers below the planet’s surface.
